For those who want to take it to the next level we now have a 3G Cellular Modem breakout! The FONA 3G has better coverage, GSM backwards-compatibility and even sports a built-in GPS module for geolocation & asset tracking. This all-in-one cellular phone module with that lets you add location-tracking, voice, text, SMS and data to your project in a single breakout.

This module measure only 1.75"x1.6" but packs a surprising amount of technology into it's little frame. At the heart is a powerfull GSM cellular module (we use the latest SIM808) with integrated GPS. This module can do just about everything

Please note! We've had a lot of requests for a 3G cell module and we're happy to oblige but this module has many small differences between it and the FONA 800 and 808, so it is not a drop-in replacement! In particular the data functionality is not as easy to use. We are adapting our FONA library to support the 3G chipset and right now we have SMS, calling, and basic functionality working but it will be a while until we get full GPRS TCP/IP and HTTP support. Also, the GPS is not as fast and low-power as the one on the FONA 808. We recommend this module for people who are able to handle a more advanced experience.Beginners will like our FONA 80x series more.

Sounds great, right? So we kitted out this fine module onto a little breakout with all the extras you need to make your next project shine

Onboard LiPoly battery charging circuitry so you can take your project on the go. Use any 500mAh+ LiPoly or LiIon battery and recharge over the MicroUSB when necessary. Two LEDs let you know when its charging and done

Standard 4-pole TRRS headphone jack. Use any 'Android' or 'iPhone'-compatible headset with mic

Breakouts for external 8Ω speaker and electret mic if you don't want to use a headphone

Level shifting circuitry so you can run it with 2.8V to 5V logic.

uFL connections for external antennas

Indicator LEDs for power and network connectivity

Standard SIM slides into the back

On its own, this module can't do anything. It requires a microcontroller to drive it! We suggest and use an Arduino but any 3-5V microcontroller with a UART can send and receive commands over the RX/TX pins.

You will also need some required & recommended accessories to make FONA 3G work. These are not included!

SIM Card! A 2G or 3G Mini SIM card is required to do anything on the cellular network.

TRRS 4-Pole Headset - Not required but it'll be tough to make a phone call without it. Any 'iPhone' or 'Android' compatible (but not iPhone original) should work. We tried about 10 different ones, and basically the more expensive once are more comfortable and louder but our official iPhone headset mic did not work.
